Hello,
My date of birth in birth certificate and passport is different.In my visa the date of birth in passport is recorded.Is it possible to change the date of birth in Visa?Whom I should contact to do the same?Please advise.
Well, first you need to get your passport corrected and then go for the visa correction. It can be done, you should start with passport and maybe re-apply for visa stamping or dropbox to get it corrected.
